[0002] The aerosol generating device or atomizing assembly generally includes a container for storing an aerosol generating substrate and a heater, wherein the storage container may be in an open state at all times, or provided with a switch with a closing and opening function. When used by a user, the heater heats the aerosol generating substrate in the storage container to generate an aerosol, which may act on the user, or the user may inhale or take the aerosol to achieve a satisfying or therapeutic effect.

[0003] For example, electronic cigarettes are used as a substitute for traditional cigarettes. In essence, they are a kind of smoke oil atomizer. Currently, electronic cigarette products on the market are devices that use power to drive the atomizer to atomize the smoke oil to form simulated cigarette smoke. Compared with traditional cigarettes, electronic cigarettes can meet the physiological needs of users while avoiding harmful substances such as tar and carbon monoxide brought by traditional cigarettes.

[0082] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0083] In addition, the terms “upper”, “lower”, “left”, “right”, “axial direction”, “radial direction”, etc. used in the following description should not be construed as limiting the present invention.

[0084] [First embodiment]

[0085] The first embodiment of the present invention is Figure 1-7 As shown, the aerosol generating device of the present invention includes a driving part 1, which can move between a first position and a second position; a liquid storage part 2 has a liquid outlet 21; a heating part 3 is electrically connected to a circuit; when the driving part 1 moves to the first position, the liquid outlet 21 on the liquid storage part 2 is in a closed state, and the circuit is in a disconnected state, so the heating part cannot work and generate heat; when the driving part moves to the second position, the above-mentioned liquid outlet 21 is in an open state, the liquid in the liquid storage part 2 enters the heating part 3 from the liquid outlet 21, and the circuit is in a connected state, and the heating part 3 works and generates heat. The present invention relates to a device that generates aerosol by heating a liquid using a heating part, and its application field can be, for example, an aerosol heating device such as an electronic cigarette, or a steam generating device, etc. The liquid in the liquid storage part includes but is not limited to a pure liquid, and can also be a sol-like, solid-liquid mixed substance, as long as it can flow out of the liquid outlet in the form of a fluid and reach the heating part, it can be called the liquid of the present invention. For example, in the field of electronic cigarettes, the liquid in the liquid storage part can be a cigarette oil or other fluid components with fragrances, and these fluids can generate aerosols for people to inhale by heating.

[0086] When a user uses a similar aerosol generating device, the liquid outlet 21 is opened when liquid needs to be consumed, and the circuit is turned on when heating is required, so at least two triggering actions must be performed. When use is finished, the liquid flow channel and the circuit must be closed. If any one of them is forgotten to be closed, it will cause damage to the aerosol generating device. In this embodiment, the drive component 1 can trigger multiple components to open or close by performing one action. When the drive component 1 is in the first position, the aerosol generating device is equivalent to being in an unused state. At this time, the liquid will not flow out, and the circuit will not start heating, preventing unnecessary outflow of liquid and consumption of excess electricity or the risk of dry burning. When the drive component 1 is moved to the second position, the heating component 3 can also generate heat in time to atomize the liquid while the liquid flows out, ensuring that the outflowing liquid is consumed in time without residue or leakage causing waste.

[0087] For example, the movement direction between the first position and the second position of the driving component 1 can be axial, radial, or circumferential of the aerosol generating device, as long as the movement of the driving component 1 can drive the relevant components in the generating device to change in state or position to achieve the closing and opening of the liquid outlet 21 and the disconnection and connection of the circuit. Here, the first position or the second position is not limited to the driving component 1 being in one and only one certain position. In fact, as long as the driving component 1 achieves the closing of the liquid outlet 21 and the disconnection of the circuit at a certain position, and the opening of the liquid outlet 21 and the connection of the circuit at another position, it can be. For ease of understanding, the specific embodiment will be introduced by taking one movement direction of the driving component 1 as an example, but the present invention is not limited to this.

[0088] like Figure 1-7 As shown, in this embodiment, the aerosol generating device is rod-shaped, and the driving component 1 is located outside the rod and constitutes a part of the outer wall of the aerosol generating device, or the driving component 1 is a part of the outer shell of the aerosol generating device. The movement of the driving component 1 between the first position and the second position can be completed by the user performing a push-pull operation, which allows the driving component 1 to move up and down along the axial direction of the aerosol generating device. Figure 1 , Figure 2 The two states of the aerosol generating device when it is turned on and turned off are shown. In addition, the operating action can also be designed to be pulling, rotating, pressing, etc., and for this purpose, the structure of the driving component 1 and the connection mode with other connecting components are adjusted and changed accordingly.

[0089] Regarding the structure of closing and opening the liquid outlet 21, the aerosol generating device of this embodiment may include a sealing body 4, and the driving component 1 can drive the relative position relationship between the sealing body 4 and the liquid outlet 21 to change between the first relative position and the second relative position by movement. When the driving component 1 is in the first position, the sealing body 4 and the liquid outlet 21 are in the first relative position, at which time the sealing body 4 seals the liquid outlet, the liquid storage component 2 is sealed, and the liquid cannot flow out. When the driving component 1 is in the second position, the sealing body 4 and the liquid outlet 21 are in the second relative position, the sealing body 4 releases the seal of the liquid outlet 21, and the liquid outlet 21 in the liquid storage component 2 is in an unsealed state, that is, the liquid outlet 21 can be partially or fully opened, at which time the liquid in the liquid storage component 2 can flow out from the liquid outlet 21, and then reach the heating component 3 to be atomized. The so-called change in the relative position relationship between the sealing body 4 and the liquid outlet 21 can be caused by the displacement of the sealing body 4, or it can be caused by the displacement of the liquid storage component 2. For example, a direct or indirect connection relationship is established between the driving component 1 and the liquid storage component 2, so that the driving component 1 can drive the liquid storage component 2 to move. The connection between the driving component 1 and the liquid storage component 2 can be completed by an intermediary connection. The driving component 1 is fixedly connected to the intermediary, and the intermediary is fixedly connected to the liquid storage component 2, so that the driving component 1 can drive the intermediary to move by moving, and then drive the liquid storage component 2 to move. The connection between the intermediary and the driving component 1 and the liquid storage component 2 can be a variety of fixed connection forms such as welding and clamping. The structure of the intermediary is diverse. In this embodiment, a liquid storage shell 5 surrounding the liquid storage component can be used. Figure 3-4 As shown, it can be seen that there is a snap-fit ​​structure at the connection position between the driving component 1 and the liquid storage shell 5, and a hook is provided on the top of the liquid storage shell 5. The number of hooks is not limited. When the liquid storage component 2 is installed in the liquid storage shell 5, the hook on the liquid storage shell 5 can hook the liquid storage component 2. Further, the extended hook has a deformable feature, so that the liquid storage component 2 can be installed or separated from the liquid storage shell 5 by rotating, twisting, pulling out, inserting, etc. the liquid storage component 2 or the liquid storage shell 5. After the liquid is exhausted, a new liquid storage component 2 can be replaced.

[0090] like Figure 3-4The liquid storage shell 5 shown is connected to the liquid storage component 2, and there is a gap between the liquid storage shell 5 and the liquid storage component 2, which can form an airflow channel. The aerosol formed by heating the liquid by the heating component 3 can reach the upper port of the aerosol generating device from the airflow channel for the user to use, for example, in the form of ingestion or suction. The connection position between the intermediary and the liquid storage component 2 is located at the end of the liquid storage component 2 along the axial direction of the aerosol generating device, such as the upper end and the lower end of the liquid storage component 2. If the connection position between the intermediary and the liquid storage component 2 is located in the above-mentioned airflow channel, there will be a physical barrier in the airflow channel, which may increase the possibility of the formed aerosol condensing into droplets in the airflow channel. Therefore, this embodiment connects the hook 51 on the liquid storage shell 5 to the upper end of the liquid storage component 2, which is beneficial to reduce the contact between the aerosol and the physical barrier during the circulation process, thereby reducing the condensation of the aerosol. As shown Figure 3-4 As shown, the upper end of the liquid storage component 2 can be assembled with a liquid storage cavity cover 23, and the liquid storage cavity cover 23 can be fixedly connected to the liquid storage component or integrally formed. Further, the liquid storage cavity cover 23 can be provided with a shape that can be engaged by the hook 51, so as to facilitate the connection between the liquid storage housing 5 and the liquid storage component 2.

[0091] Furthermore, if Figure 3-6 As shown, the sealing body 4 of this embodiment includes a sealing column 41. When the driving component 1 is in the first position, the sealing column 41 blocks the liquid outlet 21. The blocking method is, for example, plugging, embedding, abutting, covering, etc. When the driving component 1 is in the second position, the sealing column 41 can leave the liquid outlet 21, or as shown in FIG. Figure 3 The portion shown is away from the liquid outlet 21, as long as the blockage of the liquid outlet 21 can be released. Further, the sealing column 41 can be cylindrical, or when the liquid outlet 21 is a square opening, the sealing column 41 can be designed in the form of a prism. Further, the sealing column 41 gradually increases radially or gradually decreases radially along its length. Figure 6 As shown, the length direction of the sealing column 41 is, for example, the axial direction of the aerosol generating device, and the radial dimension of the sealing column 41 gradually increases along the x direction. When the driving component 1 moves from the second position to the first position, the driving component 1 drives the sealing body 4 in a direction close to the liquid outlet 21 (in the same direction as the liquid outlet 21). Figure 6 When the driving component 1 moves from the first position to the second position, the sealing column 41 is driven away from the liquid outlet 21 (in this embodiment, the sealing column 41 moves in the opposite direction of the x direction, for example, upward), or only drives the liquid storage component 2 to move along the x direction, and the sealing column 41 is inserted into the liquid outlet 21 to achieve blocking of the liquid outlet 21. Figure 6The sealing column 41 can be moved in the x direction (e.g., downward) or only move the liquid storage component 2 away from the sealing column 41 (upward) to release the sealing column 41 from blocking the liquid storage component 2. Similarly, the sealing column 41 can also be gradually reduced in radial dimension along the x direction. In this case, the sealing column 41 can be fixed in the liquid storage component 2. When the sealing column 41 is embedded in the position of the liquid outlet 21, if the liquid outlet 21 is to be opened, the driving component 1 can be used to drive the liquid storage component 2 to move in the x direction. Figure 6 During the movement in the x direction, a gap appears between the sealing column 41 and the liquid outlet 21, and the liquid can flow out.

[0092] Furthermore, if Figure 6 and Fig. 9 As shown, in the above embodiments, the sealing body 4 further includes a sealing cavity 42, the sealing column 41 is located inside the sealing cavity 42, and the port where the liquid outlet 21 of the liquid storage component 2 is located is embedded in the sealing cavity 42. The bottom of the sealing cavity 42 is also provided with an inlet 44. Figure 6 When the liquid storage component 2 moves upward away from the sealing body 4, the liquid flows out of the liquid outlet 21 and enters the heating component 3 through the inlet 44. Furthermore, a sealing ring 22 can be provided at the port of the liquid storage component 2, and the sealing ring is made of, for example, a silicone material, so that the joint between the port of the liquid storage component 2 and the sealing cavity 42 is further sealed. In this embodiment, when the liquid storage component 2 moves upward, a relatively negative pressure space is formed between the port of the liquid storage component 2 and the sealing cavity 42, which adds additional power to the liquid in the liquid storage component 2 to flow down when the user just starts to use it.

[0093] With regard to disconnecting and connecting the circuit, the aerosol generating device of the present invention further includes a circuit switch, and the driving component 1 can drive the circuit switch to move between the disconnected circuit position and the connected circuit position by movement. For example, the circuit switch is selected as the button 83, and when the driving component 1 is in the first position, the driving component 1 presses the button 83, and the circuit is connected; when the driving component 1 is in the second position, the driving component 1 releases the pressing of the button 83, and the circuit is disconnected. In another embodiment, the aerosol generating device can also be designed so that the circuit is disconnected when the button 83 is pressed, and the circuit is connected when the button 83 is not pressed.

[0094] Furthermore, if Figure 5-6 and Figure 8 As shown, the driving component 1 includes a concave portion 16 that is recessed relative to the key 83 and a convex portion 17 that protrudes relative to the key 83. As the driving component 1 moves upward and reaches the second position, the convex portion 17 reaches the key 83. Since the convex portion 17 is larger than the concave portion 16, the convex portion 17 is larger than the concave portion 16. Figure 6The convex part 17 is closer to the key 83 in the direction of the middle arrow y, so the convex part 17 will apply pressure to the key 83 to press it; as the driving component 1 moves downward and reaches the first position, the concave part 16 reaches the key 83, and the concave part 16 is farther away from the key 83 in the horizontal direction than the convex part 17. At this time, the concave part 16 only covers the key 83 but does not have a pressing effect, and the key 83 is released. It can also be arranged that the convex part 17 reaches the key 83 when the driving component 1 reaches the first position, and the concave part 16 reaches the key 83 when the driving component 1 is at the second position. The so-called concave part 16 and convex part 17 here do not only refer to the absolutely concave and absolutely convex parts on the driving component 1 relative to the outside world, but can also be two parts that are both convex relative to the outside world, but only one is more protruding than the other, which can also ensure that one is more protruding than the other. Figure 6 In the direction of the middle arrow y, it is closer to the button 83. Similarly, it can also be set to two parts that are both recessed relative to the outside world. The principle is the same and will not be repeated here. In addition, the pressing and releasing actions of the button 83 can also be achieved through other structures. For example, when the driving component 1 contacts the button 83, the button 83 is always in a pressing state. When the driving component 1 moves upward, the driving component 1 leaves the button 83, so that the button 83 is released and not pressed.

[0095] In another embodiment, if Fig.11 As shown, the circuit switch can be set in the form of a paddle 71. The relevant structure in the figure has been simplified and is only shown schematically. Accordingly, two protrusions can be set on the driving component 1, namely, a protrusion 72 and a protrusion 73. The driving component 1 can be arranged along Fig.11 The driving component 1 moves up and down in the direction indicated by the arrow. When the driving component 1 moves upward, the protrusion 73 drives the paddle 71 to move upward, and the circuit is connected at this time; when the driving component 1 moves downward, the protrusion 72 drives the paddle 71 to move downward, and the circuit is disconnected at this time. Through the introduction of the above embodiments, it can be found that regarding the structure related to circuit connection and disconnection, the driving component 1 can drive the circuit switch to move in the same direction (which can be called same-direction drive) or in different directions (which can be called steering drive), that is, in the above embodiment, the driving component 1 moves up and down, and the button 83 serving as the circuit switch moves left and right. This driving mode of same-direction drive and steering drive can also be used in other components in the aerosol generating device of the present invention.

[0096] In addition, the movement direction of the driving component can also be circumferential movement. The sealing body is configured to have a porous cover structure, and the circuit switch is a paddle structure. When the driving component is in the first position, the solid part of the cover structure covers the liquid outlet of the liquid storage component, the liquid outlet is in a closed state, and the paddle switches the circuit to a disconnected state. The driving component is rotated to make it move circumferentially. When it moves to the second position, the porous part in the cover structure is opposite to the liquid outlet of the liquid storage component. At this time, the liquid outlet is in an open state, and the paddle also switches the circuit to a connected state.

[0097] In the above embodiment, the driving component 1 drives the liquid storage component 2 to move on the one hand, and drives the circuit switch to move on the other hand. In the present invention, when the driving component 1 moves from the first position to the second position, it includes a variety of situations, for example, (1) during the movement of the driving component 1, the opening of the liquid outlet 21 and the power-on of the circuit switch occur simultaneously; (2) during the movement of the driving component 1 to the second position, the liquid outlet 21 is first opened, and then the circuit switch is powered on; (3) during the movement of the driving component 1 to the second position, the circuit switch is powered on first, and then the liquid outlet 21 is opened. As long as the opening of the liquid outlet and the connection of the circuit are achieved when the driving component 1 reaches the second position, the above examples (1)-(3) are all within the protection scope of the present invention. Similarly, when the driving component 1 moves from the second position to the first position in the present invention, it also includes a variety of situations, for example, (4) during the movement of the driving component 1, the closing of the liquid outlet 21 and the disconnection of the circuit occur simultaneously; (5) during the movement of the driving component 1 to the first position, the liquid outlet 21 is first closed, and then the circuit is disconnected; (6) during the movement of the driving component 1 to the first position, the circuit is disconnected first, and then the liquid outlet 21 is closed. As long as the liquid outlet is closed and the circuit is disconnected when the driving component 1 reaches the first position, the examples (4)-(6) above are all within the scope of protection of the present invention. Since the time spent moving between the first position and the second position when the user drives the driving component 1 to move is relatively short, even if the aerosol generating device is designed as described in (2), (3), (5), and (6) above, as long as the user drives the driving component 1 to the second position or the first position, the effect of opening the circuit while opening the liquid outlet and closing the circuit while closing the liquid outlet can still be achieved macroscopically. The examples of various situations in this paragraph are also applicable to the structure in [the second embodiment].

[0098] Furthermore, if Figure 6As shown, the aerosol generating device of this embodiment further includes an air outlet 34. When the driving component 1 is in the first position, the air outlet 34 is closed. When the driving component 1 is in the second position, the air outlet 34 is opened. The aerosol generated by the heat generated by the heating component can flow out from the air outlet 34. This embodiment realizes the closing and opening of liquid, electricity, and gas through the movement of the driving component 1, and further prevents excess liquid from leaking from the air outlet 34 when the aerosol generating device is not in use. Referring to the description in the previous paragraph, in the process of the driving component 1 moving from the first position to the second position, the opening of liquid, electricity, and gas can occur simultaneously or in steps; in the process of the driving component 1 moving from the second position to the first position, the closing of liquid, electricity, and gas can occur simultaneously or in steps. Further, the aerosol generating device of this embodiment further includes an airflow switch body 6. The driving component 1 can drive the airflow switch body 6 to move between the air outlet closing position and the air outlet opening position by movement. Specifically, as Fig.10 As shown, the airflow switch body includes a shielding body 61. When the driving component 1 is in the first position, the shielding body 61 covers the air outlet 34. The shielding body 61 can be a cover sheet, or as shown in FIG. Fig.10 The annular body shown in the figure can have a sealing effect on the shielding of the air outlet 34, or it can only cover the air outlet 34, as long as it can produce the effect of air blocking. In this way, when the user inhales when using the aerosol generating device, he can feel that the inhalation is blocked, and thus realize that he has not yet turned on the device. The airflow switch body 6 can also include a non-shielding body 62. When the driving component 1 is in the second position, the non-shielding body 62 is connected to the air outlet 34, and the aerosol can flow out through the non-shielding body 62. The non-shielding body 62 can be, for example, a porous or hollow structure, or it can be Fig.10 The structure of multiple empty slots in the airflow switch body. When the driving component 1 moves upward, it drives the airflow switch body 6 to move upward. At this time, the non-shielding body 62 reaches the air outlet 34, so that the air outlet 34 is connected to the airflow channel formed between the liquid storage component 2 and the liquid storage shell 5, and the generated aerosol can flow to the outlet at the upper end of the aerosol generating device for the user to perform actions such as inhalation. When the driving component 1 moves downward, the shielding body 61 reaches the air outlet 34 to complete the shielding of the air outlet 34. The position distribution of the shielding body 61 and the non-shielding body 62 in the airflow switch body in this embodiment can also be adjusted according to the different aerosol generating devices. In other embodiments, the airflow switch body 6 can also be set to a structure with only the shielding body 61, so that the air outlet 34 can be opened for ventilation as long as the shielding body 61 leaves the air outlet 34.

[0099] Furthermore, if Figure 5-6 , Figure 8As shown, the airflow switch body 6 can be arranged inside the driving component 1. The driving component 1 is a part of the shell of the aerosol generating device and has a cavity structure. The interior has a second protrusion 11. The airflow switch body is located inside the cavity of the driving component 1 and abuts against the second protrusion 11. The second protrusion 11 can be Figure 8 The middle convex ring structure may also be composed of multiple protrusions. The abutment method may be to place the airflow switch body on the second protrusion 11, or to abut with the second protrusion 11 in a fixed connection. The outer layer of the driving component 1 may include a texture and / or material that increases friction, such as Figure 7 It can be seen that there are lines on the driving component 1 that increase the friction force. For example, when a user pushes or pulls the driving component 1 to open the aerosol generating device, a larger friction force facilitates the user to use.

[0100] In addition, in each of the above embodiments, the aerosol generating device further includes a reset elastic body 7. When the driving component 1 is in the first position, the reset elastic body 7 is in a natural state; when the driving component 1 is in the second position, the reset elastic body 7 is in a deformed state, and at this time the reset elastic body 7 has a tendency to drive the driving component 1 back from the second position to the first position. By providing the reset elastic body 7, after the user has used the aerosol generating device, even if the user does not actively drive the driving component 1 from the second position to the first position, the reset elastic body 7 will drive the driving component 1 back to the first position through its own elastic force. The reset elastic body is, for example, a reset spring or a spring. Figure 5-6 As shown, one end of the return spring 7 is fixed, and the other end abuts against the driving component 1. For example, in this embodiment, a first protrusion 43 is provided on the outer wall of the sealing cavity 42. The first protrusion 43 can be as follows: Fig. 9 The one or more protrusion structures shown in the figure may also be a protrusion ring structure. Figure 5-6 As shown, the first coil or the first few coils of the upper end of the reset spring 7 are hung on the first protrusion 43 of the sealing cavity 42 to fix one end of the reset spring 7. The other end is nested on the airflow switch body 6 and is included in the driving component 1 together with the airflow switch body 6 and abuts against the second protrusion 11 in the driving component 1. Of course, the reset spring 7 can also abut against the second protrusion 11 in a fixed connection.

[0101] Regarding the circuit structure of the aerosol generating device, such as Figure 7 As shown, the aerosol generating device in this embodiment includes an electrode 81, the center of the electrode 81 is a hollow structure, so that air can flow into the heating component 3 through the electrode. In addition, the components include: a main body shell 12, a decorative strip 13, an electrode connecting sleeve 82, a battery bracket 8, a switch PCB 85, ​​a PCB pressure plate 84, a battery 86, a charging PCB 87, an end cover 14 and a decorative sheet 15, wherein the decorative sheet 15 plays a decorative role in appearance, and the button 83 plays a role of switching the circuit.

[0102] like Figure 1-7 In the embodiment, when the airflow switch body moves upward, the sealing body 4 can also limit the movement of the airflow switch body 6. In addition, the heating component 3 in the above embodiments may include a heating element 31, a heating element rubber sleeve 32, and a heating element mounting seat 33. The heating element 31 is, for example, oil storage cotton, a ceramic body, a porous heating metal body, or a component that can generate heat by ultrasonic vibration. The liquid flowing out of the liquid outlet 21 will enter the heating element 31. Embedding the heating element 31 in the heating element rubber sleeve 32 can further prevent the liquid flowing out of the liquid outlet 21 from leaking out at will, and at the same time has a heat insulating effect. An atomization chamber can be formed below the heating component 3, and the aerosol generated by the heating of the heating element 31 flows downward to the atomization chamber, and then flows out through the air outlet 34.

[0103] The aerosol generating device in the specific embodiment of the present invention can realize the activation of multiple parts by one action, and the reset elastic body allows the device to be closed automatically, which is simple and convenient to use.

[0104] [Second embodiment]

[0105] The second embodiment of the present invention refers to Figure 12-14 The second embodiment relates to an aerosol generating device, which can also be called an atomizing assembly. The atomizing assembly in the second embodiment of the present invention comprises a liquid storage component 1, a sealing body 2, a liquid guiding component 21 for absorbing liquid, and a driving component.

[0106] The liquid-conducting component 21 here includes, for example, liquid-conducting cotton, ceramic parts, a thin tube bundle (a bundle of closely arranged thin tubes, the gaps between the thin tubes form capillaries, which absorb liquid through capillary action and then conduct liquid), etc. The liquid-conducting component 21 of the present invention can be a component that simply has a liquid-conducting function, and cooperates with and connects to a heating component to atomize the liquid, or it can be a liquid-conducting component with a heating function, such as a ceramic rod with a heating wire or a heating film inside, or a thin tube bundle wrapped with a heating coil outside. As long as the component can play a liquid-conducting role, it can be regarded as a liquid-conducting component in the present invention.

[0107] The liquid storage component 1 includes a liquid outlet 13, and the liquid (such as tobacco oil, nicotine or other liquid substrates capable of generating aerosol, and the present invention does not impose any particular limitation on the liquid) stored in the liquid storage component 1 can be discharged from the liquid outlet 13. The liquid outlet 13 can have various forms and shapes, such as a hole shape, a groove shape, a long strip shape, or a porous membrane, and the number of the outlets can be one or more.

[0108] The driving component is used to drive the sealing body 2 to move between the fifth position and the sixth position. When the sealing body 2 is in the fifth position, it can seal the liquid outlet 13. When the sealing body 2 is in the sixth position, the sealing of the liquid outlet is released.

[0109] Here, the fifth position and the sixth position are not limited to a certain position of the atomizing assembly. In fact, as long as the sealing body 2 seals the liquid outlet at a certain position and unseals at another position, the liquid can be discharged from the liquid outlet 13, which are the fifth position and the sixth position described in the present invention. In other words, the present invention drives the sealing body 2 to move to different positions by a driving component to seal or unseal the liquid outlet. There are also many ways of movement. For example, when the sealing body 2 covers the liquid outlet 13, you can choose to translate in the direction parallel to the plane where the liquid outlet 13 is located, or you can move in the direction perpendicular to the plane where the liquid outlet 13 is located to leave the liquid outlet 13. The sealing method can be a covering seal, or the sealing body 2 can be embedded in the liquid outlet 13 to seal. When the sealing body 2 covers or embeds the liquid outlet 13, the liquid no longer flows out of the liquid outlet 13, and the position where the sealing body 2 is located can be called the fifth position. When the sealing body 2 leaves or partially leaves the liquid outlet 13, the sealing body 2 does not completely cover or completely block the liquid outlet 13, and the liquid can be discharged, and the position where the sealing body 2 is located can be called the sixth position. When the sealing body 2 releases the seal on the liquid outlet 13 , the liquid guiding component 21 is communicated with the liquid outlet 13 , so that the liquid in the liquid storage component 1 can be discharged from the liquid outlet 13 into the liquid guiding component 21 .

[0110] Furthermore, there are many ways for the driving component to drive the seal 2 to move. This embodiment stipulates that it can be divided into same-direction driving and steering driving according to the direction of the force. When driving, when the direction of the force generated is the same as the direction of the seal movement, it is called same-direction driving. For example, a push rod is set, and the push rod is connected to the seal 2. For ease of understanding, refer to Fig.12 The position relationship, Fig.12 A cross-sectional view of an electronic cigarette including the atomizer assembly of this embodiment Figure 1 The push rod is connected to the sealing body 2 and extends axially along the shell 51 of the atomizer. The sealing body 2 can be pushed up and down by the push rod moving up and down. Further, the driving component includes a push body 3 and a displacement accessory 4. The push body 3 is, for example, a paddle, which moves up and down when it is paddled, driving the displacement accessory 4 to move up and down, thereby pushing the sealing body 2 to move up and down.

[0111] When the direction of the force generated is different from the direction of the seal body movement, it is called steering drive. Fig.12, the driving component applies a force along the radial direction of the housing 51, so that the sealing body 2 can move axially along the housing 51. Specifically, the driving component includes a pusher 3 and a displacement accessory 4, and the pusher 3 and / or the displacement accessory 4 have an inclined surface, that is, at least one of the pusher 3 and the displacement accessory 4 has an inclined surface. When the pusher 3 is driven to move, the pusher 3 and the displacement accessory 4 slide relative to each other along the inclined surface direction of the inclined surface structure, driving the displacement accessory 4 to move, and then driving the sealing body 2 to move.

[0112] The relative sliding portion between the pusher 3 and the displacement accessory 4 may have various variations, such as Figure 24-25 The figure shows the structural schematic diagram and motion schematic diagram of the relative sliding part between the pusher 3 and the displacement accessory 4 (only part of the structure of the displacement accessory 4 is shown in the figure). The pusher 3 may include a sphere or an extended straight rod, and the part of the displacement accessory 4 that contacts the pusher 3 is an inclined surface. Figure 24-25 When moving in the direction of the arrow x, the sphere or straight rod and the inclined plane slide relative to each other along the y direction of the inclined plane, thereby promoting the displacement accessory 4 containing the inclined plane to move in the z direction of the figure. Of course, the pusher 3 may also include an inclined plane, and the displacement accessory 4 may include a sphere or an extended straight rod, which will not be described in detail here.

[0113] like Fig.12 As shown, the pusher 3 further has a first inclined surface 31, and the displacement accessory 4 has a second inclined surface 41. The first inclined surface 31 fits with the second inclined surface 41. When the pusher is Fig.12 When the first inclined surface 31 and the second inclined surface 41 move to the right, the first inclined surface 31 and the second inclined surface 41 slide relative to each other, driving the displacement accessory 4 to move upward. The first inclined surface 31 and the second inclined surface 41 can also be placed in a parallel position, and a ball is arranged between the two inclined surfaces, so that the two inclined surfaces can slide relative to each other. In this embodiment, there are two first inclined surfaces 31 and second inclined surfaces 41, respectively, and they can be one or more. Further, the pusher 3 can be set as follows Fig.12 The button structure shown is easy to use. Fig.12 For example, when a force is applied to the pusher 3 in the radial direction of the housing 51, the above-mentioned inclined surface structure can drive the displacement accessory 4 to move in the axial direction, thereby driving the sealing body 2 to move in the axial direction. The atomization assembly in this embodiment is ergonomically designed, and the user can operate it conveniently and have a good experience when using it.

[0114] like Fig.12When the pusher 3 is a button structure, the sealing body 2 moves upward when the button is pressed to release the seal of the liquid outlet 13, and when the button is released, the sealing body moves downward to seal the liquid outlet 13. Furthermore, the atomizer assembly further includes a return spring 23, which can further ensure that the sealing body 2 returns to the position of sealing the liquid outlet 13 when the button is released.

[0115] In a specific embodiment of the present invention, the sealing body 2 can be fixedly connected to the liquid guiding component 21, so that when the driving component drives the sealing body to move, the liquid guiding component 21 will also move together. Further, when the driving component is selected as the above-mentioned pusher 3 and displacement accessory 4, the pusher 3 drives the displacement accessory 4 to move, thereby driving the sealing body 2 and the liquid guiding component 21 to move together.

[0116] Specifically, the displacement accessory 4 can be fixedly connected to the liquid guide component 21, such as Figure 12-23 As shown, the liquid guide component 21 is nested in the displacement accessory 4. Further, the specific structure of the displacement accessory 4 is as follows Figure 15-17 The displacement accessory 4 has a limiting sleeve 42 , and the liquid guiding component 21 is embedded in the limiting sleeve 42 . Fig.16 The cross-sectional view of the displacement fitting 4 Figure 1 , it can be observed that there is a second inclined surface 41. Further, Fig.17 A cross-sectional view of the displacement fitting 4 from another direction Figure 2 It can be found that the displacement accessory 4 also includes an electrode contact 43 and an electrode contact 44, which can be respectively connected to Figure 2 The electrode conductor 32 and the electrode conductor 33 (for example, an electrode sheet structure) shown in the figure are connected. The electrode conductor is connected to the first electrode 53 and the second electrode 54 to form a heating circuit, so that the liquid guided by the liquid guiding component 21 can be heated. It can be seen from the figure that the upper and lower end faces of the displacement accessory 4 are both hollow structures, so that they can be connected to the air flow channel in the atomization component. When the liquid absorbed by the liquid guiding component 21 is heated, the generated aerosol can pass through the displacement accessory 4 to reach the air flow channel. Furthermore, in addition to the gap between the second inclined surface 41 and the electrode contacts 43 and 44, the solid part where the second inclined surface 41 is located is also made into a hollow structure, which expands the airflow circulation area and makes the airflow more uniform. In addition, Figure 15-17 The displacement fitting 4 cooperates with the pushing body 3 to support the liquid guiding component 21 .

[0117] Furthermore, if Fig.13 As shown, Fig.13 A cross-sectional view of the electronic cigarette including the atomizer assembly of this embodiment from another direction Figure 2. In this embodiment, the atomization assembly also includes a heating component 22, and the heating component 22 is, for example, a heating wire as shown in the figure. The pushing body 3 drives the displacement accessory 4 to move between the third position and the fourth position. When the displacement accessory 4 is in the third position, the electrode contact 43 and the electrode contact 44 are connected to the electrode conductor 32 and the electrode conductor 33 respectively, so that the heating component 22 generates heat to heat the liquid absorbed by the liquid guiding component 21; when the displacement accessory 4 is in the fourth position, the electrode contact 43 and the electrode contact 44 are disconnected from the electrode conductor 32 and the electrode conductor 33 respectively, and the heating component 22 stops generating heat. The third position and the fourth position here are also not limited to a certain position of the atomization assembly. As long as the position can achieve the above-mentioned connection and disconnection effects, it belongs to the scope of the present invention.

[0118] Further, the displacement accessory 4 moves to the third position while the sealing body 2 moves to the sixth position, and / or, the displacement accessory 4 moves to the fourth position while the sealing body 2 moves to the fifth position. That is, the connection between the electrode contact and the electrode conductor and the release of the seal of the liquid outlet 13 by the sealing body 2 are performed synchronously, or the disconnection between the electrode contact and the electrode conductor and the sealing of the liquid outlet 13 by the sealing body 2 are performed synchronously, or the above two processes are satisfied at the same time. Other embodiments can be extended from this, for example, the sealing and release of the liquid outlet 13 by the sealing body 2 and the disconnection and connection of the circuit are not performed synchronously, and the movement of the sealing body 2 and the movement of the electrode contact can be controlled by separate drive devices. The above embodiment adopts a pusher 3 and a displacement accessory 4, that is, the sealing and release of the liquid outlet 13 by the sealing body 2 and the disconnection and connection of the circuit are realized synchronously, and the operation is simpler.

[0119] In the case where the displacement fitting 4 is moved to the third position while the sealing body 2 is moved to the sixth position, the displacement fitting reaches the third position after the sealing body 2 reaches the sixth position. Fig.13 It can be further understood that when the pusher 3 is pushed, the displacement of the displacement accessory 4 from circuit disconnection to circuit connection is greater than the displacement of the sealing body 2 from the sealing liquid outlet 13 to the unsealing liquid outlet 13. The advantage of this arrangement is that when the pusher 3 is pushed Fig.12 When the atomizer moves to the right, the liquid first flows out through the liquid guide component 21, and then the circuit is connected when the pusher 3 continues to move to the right, ensuring the supply of liquid when the atomizer assembly is just started. Furthermore, after use, due to the action of the return spring in the figure, the sealing body 2 returns to the original position of sealing the liquid outlet 13, and the displacement accessory 4 returns to the disconnected position to prevent oil leakage and dry burning.

[0120] The liquid storage component 1 can have various forms. The liquid storage component 1 in this embodiment is as follows: Figure 18-21 As shown. Figure 18-19 It is a three-dimensional view of the liquid storage component 1 in two directions, Figure 20-21 The figure is a cross-sectional view of the liquid storage component in two directions. The airflow channel can be arranged outside the liquid storage component 1. In this embodiment, a part of the airflow channel 11 is arranged in the liquid storage component 1. As shown in the figure, the liquid storage component 1 is a cavity, and two hollow pipes extend from the cavity to form the airflow channel 11. The bottom of the liquid storage component 1 is provided with an insert 14, which is fixed with the shell 51 by interference fit. In addition, the liquid storage component 1 is provided with a liquid storage cavity 15, from which Fig.18 From the perspective of Fig.19 From the perspective of , the convex body is actually a groove 12 that penetrates deep into the liquid storage cavity, and a liquid outlet 13 is provided on the groove 12, wherein the specific shape of the liquid outlet 13 is not limited, for example, the liquid outlet 13 shown in the figure is a liquid outlet structure. Furthermore, the liquid outlet 13 is provided on the side wall of the groove 12, and when the sealing body 2 is in the fifth position, the sealing of the liquid outlet 13 is achieved by embedding the sealing body 2 into the groove 12. The sealing body 2 and the groove can choose a transition fit or a clearance fit. When the transition fit is selected, the sealing body 2 fits tightly with the groove 12, similar to an interference fit, but the sealing body 2 can still slide along the side wall of the groove 12, or the sealing body 2 is selected to be an elastic material, which can both seal the liquid outlet 13 and move in the transition fit. When the clearance fit is selected, since there is only a small gap between the sealing body 2 and the side wall of the groove 12, cotton or other materials can be wrapped around the sealing body 2 to achieve the sealing of the liquid outlet 13.

[0121] Further, when the sealing body 2 is in the sixth position, the liquid guiding component 21 is embedded in the groove 12, so that when the sealing body 2 leaves or partially leaves the liquid outlet 13, the liquid outlet 13 is communicated with the liquid guiding component 21 embedded in the groove 12. Further, when the liquid guiding component 21 is embedded in the groove 12, the liquid guiding component 21 fits with the side wall of the groove 12. Such a fitting relationship will prevent the opening of the liquid outlet 13 from being too large, causing a large amount of liquid to flow out.

[0122] The present invention also provides an electronic cigarette, which uses the atomization assembly in the above embodiments. Figure 12-13 is a cross-sectional view of the electronic cigarette in this embodiment, Fig.14 FIG. 1 is an exploded view of an electronic cigarette. The electronic cigarette includes a mouthpiece 52 connected to the airflow channel, and an insulator 55 is provided between the first electrode 53 and the second electrode 54. Figure 12-23 The use of the electronic cigarette is introduced with reference to the directions of the oil circuit and the gas circuit in the electronic cigarette, but the scope of the present invention is certainly not limited thereto.

[0123] When the user is not using the electronic cigarette, the sealing body 2 blocks the liquid outlet 13, and the heating circuit inside the electronic cigarette is also disconnected and not working. When the user needs to use the electronic cigarette, he presses the pusher 3 with his hand, and the displacement accessory 4 inside the electronic cigarette slides relative to the pusher 3, that is, the displacement accessory 4 moves upward, thereby driving the liquid guide component 21 and the sealing body 2 to move upward. After the movement, the sealing body 2 no longer covers the liquid outlet 13, and the seal is released. The liquid guide component 21 also contacts and communicates with the liquid outlet 13 due to the upward movement, and the liquid flows downward along the liquid guide component 21 to reach the heating position. Due to the upward movement of the displacement accessory 4, the electrode contacts 43 and 44 in the displacement accessory 4 are connected to the electrode conductor 32 and the electrode conductor 33 respectively, the heating circuit is turned on, and the heating component 22 generates heat to heat the liquid absorbed by the liquid guide component 21 to produce aerosol. Under the user's inhalation, the airflow enters from the air inlet at the bottom of the electronic cigarette, driving the generated aerosol to flow to the airflow channel 11 and then to the mouthpiece 52 for the user to use. After the user finishes use, he releases the pushing body, and under the action of the reset spring 23, the sealing body 2 and the liquid guiding component 21 move downward to a fixed position and stop. The sealing body 2 covers the liquid outlet 13 to achieve sealing, and the electrode contact in the displacement accessory 4 is also disconnected from the electrode conductor, and the heating component 22 stops heating.

[0124] The liquid in the electronic cigarette can be added by opening the mouthpiece 52. In addition, when a thin tube bundle is used as the liquid guide component 21, compared with the traditional liquid guide component using fiber materials such as oil guide ropes, the thin tube bundle has a strong liquid guide ability, fewer smoke particles, purer aerosol components, and better suction effect. In combination with the atomization component of the present invention, it can not only make good use of the fast liquid guide speed of the thin tube bundle capillary action, but also solve the problem of liquid leakage of this type of atomization component, achieving multiple goals at one stroke.

[0125] The present invention also relates to an electronic cigarette, which may include the structure of the aerosol generating device in each of the above embodiments.

[0126] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
